@xofer `jsonip.com` can be handy too. – ceejayoz Nov 27 '12 at 18:40

Look at the edge router/firewall configuration? Hit `whatismyip.com` from the server in question? – voretaq7 Nov 27 '12 at 21:25

`curl ip.tyk.nu`, `curl ifconfig.me` – Janus Troelsen Feb 18 '15 at 18:20

Enter ifconfig
at the command line.

Note that ifconfig will show the actual IP address assigned to the network interface, where the external sources listed in comments/answers will show the IP as it appears to, er, those external sources. This may be different in some situations, so check both. – xofer Nov 27 '12 at 18:35

For example:
links -dump http://whatismyip.com | egrep "([0-9]+.){3}"
Of course you can use another site, but this is one of most popular.

I assumed that there is some kind of NAT, and public IP is not known on host itself – Tomasz Olszewski Nov 27 '12 at 18:32
